Jeff - could you work w/Nobo to get the word "historical" included in
the MIB draft as a characterization of BFD version 0 ? For example,
the following text could be added to the introduction:
because the BFD version 0 protocol is primarily of historical interest
by comparison to the widespread deployment of the BFD version 1 protocol.
Thanks,
--David

Your WG chairs and AD should be concerned that this significant flaw in
BFD version 0 (justifying a "SHOULD NOT use" recommendation) is
undocumented.
And also un-RFCed.
It was a "work in progress" that never fully saw the light of full
deployment. Vendors very quickly moved to version 1 which fixed a critical
issue in the state machine. If any version 0 survives, it's historical and
likely to be a source of operational agony rather than a useful feature.
